@mdesjardins That method comes from rails, not rspec:

Performs a GET request with the given parameters. path : The URI (as a String ) on which you want to perform a GET request. parameters : The HTTP parameters that you want to pass. This may be nil , a Hash , or a String that is appropriately encoded (application/x-www-form-urlencoded or multipart/form-data ). headers : Additional headers to pass, as a Hash . The headers will be merged into the Rack env hash. This method returns an Response object, which one can use to inspect the details of the response. Furthermore, if this method was called from an ActionDispatch::IntegrationTest object, then that object’s @response instance variable will point to the same response object. You can also perform POST, PUT, DELETE, and HEAD requests with #post , #put , #delete , and #head .
